? Useful as Input or Output Port for Microprocessors
? Functionally Identical to MC74AC373/74ACT373
? 3-State Outputs for Bus Interfacing
? Outputs Source/Sink 24 mA
? ACT573 Has TTL Compatible Inputs

簡介

MC74ACT573屬于集成電路（IC）的鎖存器。由制造生產(chǎn)的MC74ACT573鎖存器鎖存器是類似于觸發(fā)器的基本數(shù)字存儲設(shè)備，但是不同之處在于，在鎖存使能（或類似命名）信號處于有效邏輯狀態(tài)的任何時間，保持的邏輯狀態(tài)都可以改變?！巴该鳌辨i存器還允許設(shè)備輸出在鎖存使能信號有效時反映輸入的當(dāng)前狀態(tài)，而相反的是，狀態(tài)僅在保持狀態(tài)已固定時改變。
